Pen drive not able to recognize "only" on my macbook pro osx 10.7.3

Hi Everyone,
I feel as i feel i have an unique problem and cant quite understand why. I have an early 2011 macbook pro 2.3 ghz i5 processor. I have recently bought an HP v-250 W 16GB pen drive. Its formated in FAT32 and works on every other PC and MAC except for mine. My compute is unable to recongnize it and it doesnt show up in Disk Utility either. Im not sure why this is the case. Can it be because of the software version at 10.7.3. Your feedback will be most helpful. thanks

That is quite strange, I did have a similar issue with Western Digital 1.5TB External HDD a while ago. It worked on other computers just fine but not on my Mac, one day it just stopped working all together.
I am not saying that its an issue with the pen drive though. Could be either or.
The only thing that I can think of trying is to start up in Safe Mode and see if it works. If not then you can at least rule out any applications causing problems.
Let me know how you go. I will have a bit of a look in to this for you as well... I'm curious... And a little confused myself

HT3887 I m not able to found Bluetooth in my Macbook Pro. Error is Bluetooth : Not available.

I am not able to found Bluetooth in my Macbook Pro. Found error is Bluetooth not available. Please inform me.

Welcome to the Apple Support Communities
Somehow, OS X doesn't detect Bluetooth in your computer. First, reset the PRAM and the SMC, and see if you can use Bluetooth then.
If not, hold Command and R keys while your computer is starting to start in OS X Recovery, and reinstall OS X. If, after reinstalling OS X, you can't use Bluetooth, there's a hardware issue with your Mac, so take your Mac to an Apple Store or reseller

External drive not working on iMac, but works on Macbook Pro

I have read a few different threads relating to this question, with no real luck of a permanent solution.
I have an external drive that works perfectly on my Macbook Pro. My new iMac will not show the drive though (both with the current software).
The drive itself shows a power light and appears to be running/powered by the USB port.
I have tried several ports.
It does not show in Disk Utility.
The option in settings is set to show the drive in finder and on the desktop (I have checked this).
I have tried restarting the iMac.
I have also had this problem after the iMac has been turned off overnight, and turned on in the morning (and then plugging the drive in after powering on).
I resolved this issue once by turning off the iMac, removing the power cord for a few minutes, and powering it up again.
I don't think it should be something I have to do every time I would like to use the drive though - It would be very irritating if I had to do that every time.
Any advice or options here?
The iMac has only been used since Christmas day, 2014 - and has had this problem since that day (in which i solved it by the turn off/unplug thing).
Sorry, I am aware this question has been asked a lot. I haven't come across anything that is giving me a long-term solution to this problem.
Happy new year!

Some USB-powered drives are just crappy. They require too much current from the USB and cause the bus to fail or the bus can't provide enough power for it to fully spin up. You can often hear or feel them clicking periodically (like once a second) as they are trying to spin up.
If this is the case, a powered Hub, external power supply, or Y-cable will be necessary to consistently use the drive.

Hard drive won't mount - but only on one Macbook Pro

Hi guys
So I have a brand new Macbook Pro 2.4 with retina and 8gb (like 2 days old). I'm on Mavericks. This question also concerns a Lacie Rugged USB3 1TB drive, it is bus power only.
My lacie won't mount on my new mac. An identical lacie will, as will a few older other lacie drives I use for archiving and occassional long term backups. I've checked this unmountable drive on 8 different macs (friends, work, mothers) everything from other imacs, to old G5 power pcs, and even my mums ancient ibook g4. They'll all mount it. My macbook pro wont.
* It's nothing to do with ports (all ports work and power various devices) and cables (different cables also do not work, and they work with other drives).
* It does not appear in disk utility
* It does not appear in the system profiler/report even though the ports show up no trouble
* the drive powers and spins up
* i've even just formatted the drive on another computer in extended journal and it still does not appear yet will still mount on another machine
I'm tearing my hair out. Help me! Does anyone have any idea's what the **** is up with this thing?
Thanks

They'll all mount it. My macbook pro wont.
typical behavior of a SATA bridge dying
80% likelihood you have a dying SATA bridge card

Your dead external hard drive is likely fine! Great hope for your 'faulty' external HD

Why not able to access Family Share on MacBook Pro?

I am supposed to be part of a Family Share account. I can access Family Share & other family member's purchases on my iPad but NOT on my MacBook Pro that is running Maverick OS. I log into iTunes, click on the drop down window at the top where my name is located but when the window drops down Family Share is not an option nor am I able to see the names of the other family members in the group. I have tried going to "System Preferences" to "iCloud" and then try to look for "Manage Family" but it is not there. Even if I then if after getting to "iCloud" & logging into "Account Details" there is not anything about "Manage Family" or "Family Share"
Can you not participate with Family Share using Maverick OS?
I would REALLY appreciate assistance with this issue.

It appears you need Yosemite.
From the linked article:
In OS X Yosemite, go to Apple menu > System Preferences > iCloud > Manage Family, click your name, then click the Remove button in the bottom-left corner.
Family Sharing - Leave

Still not able to input video on my Macbook Pro

I have a new MacBookPro. I used to be able to use my Dazzle Hollywood Video input device, to import tapes into my Imovie program. Since I got the new computer I cannot get Imovie to see anything other than the Facetime camera. I cannot switch to the Dazzle unit. Is there some trick to getting my computer to see the VHS tape?
I have tried everything I can think of .
Thanks in advance for any help you can give.

Contact the Dazzel vendor or developer. Confirm if their software is compatible with Snow Leopard 10.6.7. Your current os is outdated.

I am not able to update iMovie to my macbook pro late 2011 which came bundled with it.

It shows that imovie update is available in the update tab, but it doesn't show in the purchased tab. iLife '11 came bundled with my Macbook Pro but when I try to update iMovie, it tells me to sign in with the apple id that I purchased it with. I have no other apple ID. Sometimes it tells me that I had to have purchased it from the app store first before I can update it. What's the solution to this problem, please. iPhoto updated with no problem. There was no update for Garage Band so I don't know if that will be a problem when an update is available. Thanks.

Thanks for the reply but that didn't work for me. The trouble was imovie wasn't showing up in my purchases even though it was saying I needed an update because it was installed on my computer. I finally contacted the itunes app store. I was told that the imovie app shows up as a purchase for my apple ID. I had to delete it from my applications folder, then repurchase it. That worked. Apple refunded the money to my card once I provided the order number to them. All is well, now.

Not able to recognize any video/audio devices using jmf and java soun

Hi ,
I need one help from your side.
Here I am expecting some clarifications from you. Before that let you my environement.
My working environment :
Eclipse tool and added jmf jar to my project I did not do any thing more.
If any thing I need to do just let me know. My target platform is MAC & UBUNTU.
Please bare with my questions.
1) I am not able to recognize any video/audio devices using jmf and java sound APIs on My system.
( I checked with the app mentioned in the http://www.java-forums.org/new-java/11201-jmf-cannot-connect-device.html )
Do we need any administrives rights for our working PC.
What is the procedure/ setup I need to follow from a java application to enable particular audio/video device since I dont about end-user system setup right.
If possible send some sample code to recognize /r detect audio device ( voice input ). It should run on both MAC and UBUNTU.
2) I run the one sample audio recording application of this link (http://www.jsresources.org/examples/SimpleAudioRecorder.java.html) which is provided by YOU.
I got output audio file and able to hear voice on UBUNTU system but not able to hear voice on MAC system.
I heared that default line in ( audio setup of the sys) is wont take any voice data on MAC.Why I made this stmt means we are getting false when using isSupported methods of JAVA SOUND API.
( like for TragetdataLine ...i,e, all ports are getting false)
I have one sample audio recording app implemented by QUICKTIME API. In this case also he taking audio ftom device only using quicetime API.
With that we are able to record and hear audio ( voice input --> not line in , external device we added some thing like SSB...)
3) In case of Video capturing DataSource, Streams are implemented by PullBufferDataSource , PullBufferStream intefaces used.
In case of Audio capturing DataSource, Streams are implemented by PushBufferDataSource, PushBufferStream intefaces used.
Can you explain the reasons ? I gone through API but i am not clear.
HOPE I WILL BE CLARIFIED EVERY THING FROM YOU.

Macbook pro osx v 10.9.5 will not recognize or play netflix dvds

My macbook pro osx 10.9.5 2.4 GHZ Intel Core i5 will not longer play any netflix dads. I have even tried 2 separate external stand alone drives hooked up to my mbp via usb and 4 different movies and one will play in any source and the discs are in brand new condition. I insert the disc into the mbp drive and you hear it trying to read the dvd about 3 times, failing, then spits it out. Over and over I have tried.
What is very strange is dvd movies that I personally own will play fine no problem.
This is the first time that I tried to watch a netflix dvd in my mbp since I did an update and I do not remember when that update was done.
Do you think there is some sort of protection on the netflix dvds that could be causing this? or maybe this osx version is faulty and not able to play or recognize rental dvds?
any ideas would be much appreciated.

Have you used DVDs that have different region codes? It may be that your DVD drive is locked for a region code different from what Netflix is programmed for.
Ciao.

I have an external hard drive but it is read only on my macbook.

I have an external hard drive but it is read only on my macbook. I have tried my friends which works on his macbook but this is also read only on mine. Do I need to change any settings?

Here's my lo-tech solution (if you have Parallels) to this frustrating problem:
Eject your hard drive.
Unplug (USB) your hard drive from the MAC .
Start Parallels.
When Windows has started, plug your drive back into the MAC.
You should get a little screen asking if you want the drive to be utilized by MAC or Windows. Select Windows.
Use Windows to copy your files over to the hard drive.
This is less than ideal and not a long-term solution, but I was afraid of attempting any reformatting since I have many files on my hard drive.
Just remember that Windows has to be running first, before you plug in your hard drive.

Can I purchase Mountain Lion and make a flash drive bootable? I do not want to install it on my Macbook Pro. I have Snow Leopard on my Macbook Pro now, and due to my hard drive needing repair I need to boot off of another source, like my flash drive.

Can I purchase Mountain Lion and make a flash drive bootable? I do not want to install it on my Macbook Pro. I have Snow Leopard on my Macbook Pro now, and due to my hard drive needing repair, I need to boot off of another source, like my flash drive. I am in Paris and my Snow Leopard DVD is in Texas.

Mac OS X has a built-in disk diagnostic and repair program called fsck or file system consistency check. Here’s how to verify and repair your startup disk with fsck. As soon as you hear the startup tone, press and hold Command-S on the keyboard. Keep holding down those keys until you see a black screen with white lettering. This is called “booting into Single User Mode.” As the Mac boots in this mode, the screen reports each step of the process. The line should end in root#. Right after the root# prompt, enter the following: /sbin/fsck -fy
If repairing the disk in single user mode fails, it means one of two things. Either your hard drive itself is failing (a hardware failure), or the directory damage on your hard drive is beyond the capability of the built-in repair procedures in OS X.

I just created a slideshow dvd in imovie, and when I hit finalize it said that it would take 7 hours to finalize. I've only had my macbook pro for 6 months, and this is the first imovie I've done...is this normal? If not how can I speed up this process?

Hi
Time needed can depend on several things.
• less than 5 GB free space on Start-up (Mac OS) hard disk = Redicolous long times AND a DVD that most probably will not work OK
Medicine - I never go under 25GB free space
• Use of strange file formats into iDVD - can force it to de-code first then re-encode - this can take long long times
I use
Video - StreamingDV as from miniDV tape Cameras - or QuickTime Movies Converted to StreamingDV
Audio - .aiff 16-bit 48 kHz - (no .mp3, .wma etc)
• Use of old Mac - My G4 600MHz took about 24 hour per hour movie. my dG5 - about 2 hours per hour (I use Pro Quality encoding)
• Pro Quality encoding - takes about x2 to process a movie
Yours Bengt W
